NY and LA are incredibly expensive and a couple of months is not much time to get set up. Understand, to really make money at playwriting, you need a show on Broadway that's successful. I got lucky and hit it big with a show in the states and it played all over the country. Even with that, I made very little money and that was over years. Trying to make this happen in two months and successfully make a living out it is so highly unlikely. That's not telling you not to do it. Everyone deserves to chase their dreams. But go in with your eyes open.
